WOL

The WOL (Wake-On-Lan) page allows you to send Wake-On-Lan (aka “Magic”) packets to your wired client devices to power them on.
The client devices must be configured to respond to WOL packets for this function to work.

For a PC to wake up from a WOL packet, it must have its WOL firmware setting enabled. Before testing scheduled WOL events in Tomato, please ensure your PC has the appropriate UEFI/BIOS menu setting enabled to recognize Wake-On-LAN packets. Most UEFI/BIOS interfaces have a Wake-On-LAN option named something like:

  • Power on by PCI-E or PCI (Asus UEFI)
  • PME Event Wakeup (AWARD BIOS)
  • Power on by PCI devices (AMI BIOS)

WOL settings in the PC's operating system also must be enabled. See here for details:

WOL functions generally assume a client PC/device starts out from an off state. If your device is in a suspend or sleep state, it may not recognize the wake signal and therefore may not wake as expected. Details for Windows can be found here:

The list of devices on this page includes:

  • Devices already active in the ARP table.
  • Devices defined in a static DHCP assignment.
  • Devices defined manually in the Dnsmaq Custom configuration field
    in the Advanced/DHCP/DNS/menu. For example:
    dhcp-host=70:EE:50:37:E8:46,myhostnamein


Some devices might appear on this page, but not have their hostname defined/displayed. You can work around this by defining them manually in the Dnsmasq Custom configuration field as described above.


There are two ways to wake up a device:

  1. Click anywhere on the device you want to wake. After clicking, you should see the (WAKE UP) text in the Wake Up button (not the button itself) briefly turn grey. This indicates that a WoL packet was sent to that device's MAC address.
  2. Type the desired MAC Address(es) of the devices to be awakened into the “MAC Address list” field, and then click the WAKE UP button.

NOTE: MAC addresses in the MAC Address List field are remembered, as long as have clicked Wake Up even once after entering them.
